' ppleation filed November 3, 1911. Serial. No. 658,343.

State of New Jersey, have invented certain` new and useful Improvements' in Phonographs, of which the following is a description.

My invention relatesto phonographs and more particularly to .an improved record support or holder :for such machines.

Ordinary phonograph records change 1n diameter to a considerable extent under different temperature conditions, expanding under heat and contracting under cold, whereas the supports or holders upon which the records are mounted change but little in diameter under the same conditions. As these supports orliolders are so constructed that whenthe records'are placed thereon a tight engagement will be maintained between the same and the records, it frequently happens that the records become so tightly locked in place under adecrease inA temperature that it is difficult to remove them without damage to the record surface or breaking the records themselves. The object of my inventionis to provide a record support or holder adapted to irnily hold the record and yet permit its ready'removal, my invention being an improvement on that disclosed in an application of Newman H. Holland, filed October 6, 1911, Se-

rial No. 653,155. In conformity with Athe above named object, I preferably provide a support or holder having elongated record engaging members extending longitudinally thereof and movable at an angle toward and away from the airis thereof.

My invention also contemplates the provision of means for imparting a quick and limited axial movement to the record holding `means; so that upon the cessation of the axial movement of the -said means, the momentum of the record tends to disengage the latter therefrom.

Other objects of my invention will appear more fully in the following specification and appended claims.

In order that my invention may be more fully understood, attention is hereby d1- rected to the accompanying drawing illustrating the (preferred embodiment of my invention, an in which- Figure l represents ,a vertical longitudt.

nal, section taken through the centerof the mandrel of the phonograph embodying my mventlon, a part of the frame' of the phonograph being shown in elevation; and Figs. 2, 3, 4 and 5 represent sections of theman-l drel taken on lines 2 2, 3*3, 4-1, and 5 5 respectively of Fig. 1, Figo showing a record mounted upon the mandrel.

In all of the views corresponding parts are designated by the same 'reference nul merals.

The phonograph to which my invention is I shown applied in Fig.' 1 is of Well known construction andY comprises a bed platel,

provided with standards 2 and 3. Supported at one end in the standard 3 is a stationary tube or sleeve 1 secured rigidly in;

position, as by a set screw 5. The driving shaft 6 for the phonograph is mounted to extend through the tube 4, the left hand end y of said shaft, as'shown in 1, being-roi tatable within a bearing 7 in the corresponding end of the tube or sleeve e. 'A collar or plug 8 securedrto the right' hand 'end of the shaft 6, as b'y a set screw 9 engages the corresponding e'nd of the tube fl and cooperates with 'the shaft enlargement 10 engaging the outer end of the hearing 7 to prevent the shaft from shifting longitudinallyvith respect to the tube e. Power is transmitted to the' driving shaft of the.

phonograph by means of a belt not shown) encircling the'pulley 11 rotatable on a shaft I 12 which latter is secured to the standard 2 `by a set screw or equivalent means 13. A

screw 14 or equivalent'means engages in the groove'l in the shaft 12 to'prevent movement of the pulley axially of the said shaft. The shaft 12 is axially in line with the shaft 6 to which it is adapted to be connected by a clutch 16 which is slidable back and forth upon the enlargement 10 of the driving shaft 6. Gear 17 is secured to the enlargement 10 of the shaft 6, and from this gear by connections (not shown) the feed of the phonograph is driven in the usual manner.,

AMy improved record support vor holder comprises a tubular shaft 18 secured at its outer end, as by the set screw 9, to the-col-`V lar 8 so as to rotate with the shaft 6 and provide at its inner end with a bearing 19 whereby it 'is rotatably mounted upon the tube 4.

The numeral 2O designates a flange o r KVV,

collar El inolnited upon the the inner l' d thereo' and b" a set screw .fr second .te member L3 similar to the me iber cured to the shaft 1S adjacent the 'bereoi bv a serene4 j? These rods, as shown, are preferablylcjyilindrieal in form; and, as more clearly shown in Figs. 2 and 4f, the openings thereor m the members :ZOvand extend throughoutslightly more than a semi-circle so that 'the said rods :27 are retained against displacement laterally from the said flanges and at the same time extend slightly beyond the periphery of the latter, whereby each presents an unobstructed portion adapted to engage the bore or' the record. By reason of the location of the o'oeninffs 26 slilrhtl A C D nearer the axis of the support or holder than the openings 25, the support or holder formed by the rods 2? has a slight taper to- Ward the outer end thereof, t'ne rods 2? being;`

inclined to the axis ofthe support or nolder.-

It is evident that when rods are shifted axially toward the outer end oit the support or iiolder they the more sligl'itlj;v inwardly and there-oy comme loosened or disengaged from the bore of a reeord supported thereon. lily axial movement olf thesaid rods in the opposite direction, the latter can be n ered array from the axis ot the suppfirt or holder and. brought into iii-in engagement with the bor ln order to permit nioi'ement the ro e of the record.

When the actuating oree is removed from the horizontal arm' of the lever, the latter and the member 30 are returned to their original positions by thev springs 39 and respectively. By imparting a quick thrust to the horizontal arm of the lever7 the lnomentum of the record inwrnoving toward the outer end of the holder materially facilitates the disengagement of the record from the rods Q7 upon the cessation of the movement of the latter.

'It is evident that the rods 27 maj,7 be made of any preferred shape and that numerous other' modiieations may be made in the speeiie structure disclosed Without departing from the spirit of my invention. Wish, theref re, not to be limited to the exact details shown, but l Vilhat elaimas new and desire to proteet by Letters Patent is as follows?- l, In a phonograph, a record holder eom` prising a trame or support, and a plurality' o'lelongated record engaging 'members slidable longitudinally in said frame or support and connected for simultaneous movement. substantially as described,
